流向图在行星齿轮箱故障诊断中的应用OA北大核心CSCDCSTPCD
Applications of Flow Graph to Fault Diagnosis of Planetary Gearboxes
针对行星齿轮箱诊断过程复杂和诊断结果准确率低的问题,提出了一种基于流向图的行星齿轮箱故障诊断方法.该方法通过流向图构建算法直观地表示行星齿轮箱的故障诊断知识,利用流向图约简算法删除不必要的征兆属性节点,以简洁的形式表示属性之间的因果关系,利用流向图分类决策算法确定待诊实例的故障类型.仿真和实验结果证明了该方法的准确性和直观性,为行星齿轮箱的故障诊断提供了一种新颖的解决思路.
Aimed at the problems of complex diagnosis processes of planetary gearboxes and low accuracy of diagnosis results,a fault diagnosis method of planetary gearboxes was proposed based on flow graph.In this method,a construction algorithm of flow graph was utilized to intuitively represent the fault diagnosis knowledges of planetary gearboxes. Then,a reduction algorithm of flow graph was applied to removing unnecessary condition attribute nodes. The conseq…查看全部>>
